This article describes the synthesis and characterization of novel triorganotin(IV) complexes and their potential medicinal applications. Triorganotin(IV) complexes with formulas [(SnMe3)(2)(mu-bp)(H2O)(2)], 1, and [(SnMe3)(4-NO(2)pcyd)], 2, (Me: methyl, bpH(2): 4,4'-dicyanamidobiphenyl and 4-NO(2)pcyd: 4-nitrophenylcyanamide) have been synthesized via a sonochemical process and characterized using multinuclear NMR (H-1, C-13 and Sn-119), Mossbauer spectroscopy, elemental analysis, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Compounds 1 and 2 were evaluated for their DNA/protein binding with calf thymus DNA (CT-DNA) and bovine serum albumin (BSA), respectively. The in vitro cytotoxicity of 1 and 2 was examined against A549, Du145, HeLa and MCF-7 cancer cell lines. For 1, a promising growth inhibitory effect against HeLa cells was observed that is slightly higher than that of cisplatin. Moreover, the antimicrobial activity of 1 and 2 against different strains of pathogenic bacteria and fungi were tested. The free radical scavenging ability (OH, NO) of 1 and 2 was assessed.
